Spike-08 has potentially faulty PSUs
The 500W PSUs in spike-08.
Under extreme load spikes the PSUs fail.

LOG: Server Critical Fault (Service Information: Runtime Fault, System Board, P12V Main/AUX Regulator 1 (04h))
New 865408-B21 are known good replacements.
Disabling High Efficiency Mode reduces the occurrence of the issue.
8J serial with Firmware 2.00 is known good, but a G10 I think is required to update the firmware. G9 is unable to update the firmware.
8J serial with Firmware 1.02 from experience is bad. A prime95 will cause the P12V Main/AUX Regulator issue within a few minutes.
The closest HPE document on the issue: https://support.hpe.com/hpesc/public/docDisplay?docId=a00050474en_us Note that 8J serial with firmware 1.02 is still not good from experience. Firmware 2.00 is OK.
I have set PSUs to balanced mode, instead of High Efficiency mode which reduces the likelihood of a PSU 12V trip.
spike-08 only appears to have tripped 2 times due to the PSU 12V issue. So thankfully quite rare.
